Title: Measurement method of double refraction for transparent filament
Inventor: SHIMIZU JIROU
IPC: G01M11/00
Filed: 1978-12-28
Abstract: PURPOSE:To enable to measure the double refraction of filament simply, without preparing various immersing liquids, by emitting the laser light on the filament and observing scattered light caused on the same side as the light source. CONSTITUTION:When laser light is radiated on the transparent filament 2 from the light source 1, it is incident inside the filament 2, and after reflected on the surface of the filament 2 at the opposite side to the incident side, the light outputted to the incident side and the light reflected on the surface of the filament 2 at the incident side form the scattered image. The scattered image appears on the photo detector 3 provided at the same side as the light source 1 to the filament 2. That is, with the interference between the said two lights, symmetrical interference fringes taking the direction 180 deg. to the incident ray as a center are appeared. The spread of the scattered image has close relation with the refractive index, and the distance of the interference fringes has close relation with the diameter of the filament 2. Accordingly, by measuring the spread of the scattered image and the distance of interference fringes, the refractive index of the filament 2 can be measured.

Filed: 1978-12-26
Abstract: PURPOSE: To improve the manufacturing efficiency by a method wherein an indexing mark is provided on each chip inside one wafer and read out by an electron beam irradiation to identify the chip.  
     CONSTITUTION: In addition to a wafer indexing mark 5, each different chip indexing mark 4 is formed inside each chip 3. The mark 4 is shown in a binary code indicating the presence of a member 7, which may be a metal film or an insulating film having the different reflectance from that of the groove or surroundings. Each indexing signal is read out with an electron beam exposed over the mark and the corresponding acceptable or defective data are read out from the storage through a computer. By determining the necessity of applying the production process to the chip, the loss resulted in applying the production process to the defective chip can be avoided.

Title: Ceramic substrate
Inventor: KAWAHARA KAZUO
IPC: H01L23/15
Filed: 1989-06-26
Abstract: PURPOSE:To restrain Ag from being diffused and to execute a sintering operation at a low temperature of 800 to 1000 deg.C by a method wherein a glass powder in a specific composition range is mixed with an alumina powder of a specific amount and this mixture is sintered. CONSTITUTION:A mixture of an alumina powder and a glass powder is used; the amount of the glass powder in the mixture is set to 35 to 65wt.%; a glass composition in terms of wt.% is set within ranges Al2O3 at 3 to 15, PbO at 40 to 52, Si2O at 32 to 40 and B2O3 at 2 to 8. When the ratio of the amount of the glass powder to the amount of the mixture of the alumina powder and the glass powder is less than 35wt.%, a sintering temperature becomes high. When the ratio exceeds 65wt.%, the quality as a substrate such as a strength, a moistureproof property and the like of a sintered body degrades. When the composition of the glass powder is set outside a specific range, this has a bad influence on a glass softening temperature; when Al2O3 is 3wt.% or lower, an effect of a waterproof property does not become remarkable. Thereby, it is possible to restrain Ag from being diffused so as to be negligibly small; a sintering operation can be executed sufficiently at a low temperature of 800 to 1000 deg.C.

Title: Movable element-locking mechanism for linear pulse motor
Inventor: KOBAYASHI MUTSUJI
IPC: H02K41/03
Filed: 1986-07-14
Abstract: PURPOSE:To prevent displacement of a movable element in the non-excited state by providing a means which is operated in the non-excited state to give a locking force to a secondary side magnetic circuit of the movable element. CONSTITUTION:If a coil 61 is excited, a magnetic flux is saturated at a notch 64-forming portion of a coupled magnetic path 63 and a high permeability magnetic body 66 is attracted to the notch 64-forming portion. Consequently, a biasing member 65 is attracted toward the coupled magnetic path 63 and a locking-force imparting member 69 is shunted from the movable element 51, which is then operated smoothly. On the other hand, the biasing member 65 is energized by a flat spring 67 via the magnetic body 66 when the coil 61 is not exited and the locking-force imparting member 69 is pressed against a secondary side magnetic circuit (teeth forming portion 55) of the movable element 51. Therefore, a sufficient locking force is imparted to the movable element 51, which is prevented from being displaced.

Abstract: PURPOSE: To simply reduce the life time of carrier by placing the substrate in a plasma treatment device having electrodes containing iron and copper, and treating the substrate with a gas, such as argon, oxygen or carbon fluoride so as to introduce iron and copper thereinto.  
     CONSTITUTION: A plasma treatment device 1 consisting of a vacuum enclosure 2, and water-cooled electrodes 3, 4 made of stainless copper is formed. Semiconductor substrates 5, into which life time killers are to be introduced, are placed on the electrode 3, and the enclosure 2 is made vacuous. A reaction gas, such as CF 4  is introduced into the enclosure 2 through a reaction gas introduction port 6 to set the internal pressure of the enclosure 2 to 0.01W1Torr. A high frequency current is then applied to the electrodes 3, 4 to generate plasma. Thus, the iron and copper contained in the electrode are introduced into the substrates 5, which are then withdrawn from the enclosure. The substrates 5 are then subjected to heat treatment to diffuse the iron and copper therein. This allows the life time of the substrate to be reduced to the same level as in a case where Au is used. Moreover, a chemical treatment, which is required in a case where Au is used, can be omitted.
